IMPROVEMENT IN OILERS.

Specification forming part of Letters Patent No. l l 1,068, datedJanuary 17, 1871.

To all whom, t may Concern: i

Be it known that I, A. D. LAWS, of Bridge port, in the county ofFairfield and State of Connecticut, have invented a new Improvement inOilers; and I do hereby declare the following, When taken in connectionwith the accompanying drawings and the letters of reference markedthereon, to be a full, clear, and exact description of the same, andwhich said drawings constitute part of this specification, andrepresent, iii- Figure l, a side view, and in'Fig. cal central section.

This invention relates to an improvement in oilers such as are used forejecting oil for lubricating and other purposes, the object being torender the oiler more durable than has heretofore been done, and itconsists informing the bottoni from a concavo-convex disk of temperedsteel made elastic by its shape, so that When it has been depressed toeject the oil it will certainly return to its first position.

A is the body of the oiler; B, the ejectingtube, formed from sheet metal`in the usual manner and of the usual form. C, the bottom, hasheretofore beenmade from sheet-brass, which from its nature isnotcertain to return toits original position after depression and losesits elasticity from use, often rendering the oiler useless. I form thebottom C from a- 2 a verticoncavo disk of tempered sheet-steel,thevconveX side being out, so that depressing the bottom with the thumbejects the oil, and tlie elasticity of the steel insures its return, and

as the steel cannot lose its temper by use, the bottom retains itselastic qualities so long as the oiler lasts.

In use, the lower edge of the oiler is liable to be struck against hardsurfaces, Which indent it and cause itto leak. To avoid this diflicultyI form a Wire ring, D, of the circum ference of the body at the bottom,and attach this to the bottom or edge, as seen in Fig. 2, the Wire beingof sufficient strength to sustain and prevent the injury of the edge.

In use the end of the ejecting-tube is often brought into position Whereit is liable to be jammed, and if formed from sheet metal, in the usualmanner, is frequently so mashed as to require a new tube, or the oileris rendered useless. To overcome this I form the end of the tubeslightly larger' than is usually done, and Within the end I arrange asteel bushing, a, as denoted in solid black, Fig. 2, through which aperforation is made for the passage ot' the oil. This bushing sustainsthe end and prevents the niashing of the tube, and adds very little, ir"any, expense in the construction of the tube.

I claim as my invention# The concavoconvex bottom pered to give andretain its elasticity, substantially in the manner set forth.
